Too good to be true? Removed gskill heatsinks and dropped temps by nearly 50% with a little active cooling O_O (peak 29.25c)

So.. took a risk today on one of my extra kits. Saw a few videos and posts of people removing heatsinks from their ddr5 ram kits because apparently alot of heat actually gets trapped inside rather than dispersed properly or because of the cooling pads not being efficiently touching pmic or lacking entirely, etc. saw a few different methods where people used a heatgun and even used a hairdryer.. which i have and a bottle of isopropyl for all my cpu swaps ive done in recent years so i could clean thermal paste and so on.

Normally whenever i tune anything for ram, i run a few hours of occt memory stability test to make sure theres no errors. All 4 of my ram kits typically peak at 55c when i oc them..

Today i took some time off work and was feeling adventurous.. i was like screw it, lets remove some heatsinks even though i might mess up and break somethin. So i did it.. even scratched the pcb from one of my tools used to take the heatsink off and soaked the sticks in isopropyl for awhile and removed the remaining residue.

I installed the new ram sticks thinking it wouldnt even boot up and I even slapped a jerry rigged fan with zip ties on top of them.. it posted.. i turned on expo and then did an occt test and boom.. holy moly.. im now at 03 hrs and 45 min of occt with 0 errors and both sticks peaking at 29.25C ? Holy... Its insane! Is this real life? Removing heatsinks helps this much? Obviously active cooling will help alot too.. but i didnt think removing the heatsinks would help too. Later i'll run another test after unplugging the fan and see what happens
